That case only supports one 120/140mm fan on the top. The front panel is the only location where you can fit 3x120mm or 2x140mm fans.

You're going to have to take the front facade off and mount the fans in front of the radiator. You'll want them pulling air through the front of the case into the radiator. Exhaust the warm air out the back and top of the case. Since the case came with two fans (one front, one rear), put the front fan that you removed from the case in order to install the radiator at the top of the case and have it exhaust air out the top.

I did this and it seems to be running a lot cooler. Looking for the software to see the heat but can't find it on asus. Only utility is a raid utility.

I'm going to have to say, I don't think you're going to have too much of a problem with heat, even with the radiator mounted in the front as long as you have a fan mounted at the top and rear that is exhausting air. The current rig in my signature uses the Corsair Spec Alpha case, which only supports a 240mm rad in the front. I had to move from my old 750D because the front facade broke off and left me with an eyesore. I run games, video encoding, and a development environment building projects and I've only noticed a 1-2°C difference since moving my radiator from the top exhausting out to the front bringing air in. And that's only when I'm doing multiple things at once (a game on one monitor while building a solution with about 120 projects in Visual Studio and maybe 10 browser tabs and youtube open on a second monitor).

If it's working for you now and you're not seeing any temperature problems, I think you'll be fine.

I think I'm going to leave it alone , like JBC says. Does it matter if I mount the ram in the black or silver spots? I have 2 sticks of 8gb each? I've read it can affect it depending on what position it's in..

Great, Thanks! I have them in the wrong spots then. I have them in a1, b1. Now that I'm tweaking the machine, I'm getting a fan error at boot, something about plugging into the head. Here is a diagram of how I have my fans setup. Is this correct?

Green: CPU/PUMP (aio_pump)
Yellow: front watercooler brick ( Holding 5 fans. Watercooler fans and 2 front fans. All blowing in) The watercooler is mounted on the inside of the chassis with fans blowing in. Then I have 2 fans outside chassis, under the front plate ,mounted in front of 2 of the water cooler fans, also blowing in. So the watercooler fans are pulling and the other 2 are pushing. (cpu_fan)

Purple: back fan blowing out (cha_fan1).

I'm sill going to order a large fan for the top blowing out, which I assume gets the last cha_fan2 spot?

Only the radiator fans should be on the CPU_FAN header. All case fans should be on CHA_FAN headers or connected to the PSU with molex adapters or by using a fan bus.

If you return the Deepcool, I'd recommend you get the Noctua air cooler you listed in your first post. The case you chose is just not really set up well for water cooling.

OK, I'm keeping the watercooler, I don't have the box and they won't take it back without a big fee. It's mounted in there nice and the temp is staying at 41 so i'm ok with that, right? Also, The watercooler came with a 4 fan block. Three of the spots are black, for the 3 fans I'm assuming, the 4th is white for some reason? So should I plug the 3 cooling fans into that, then into the cpu_fan? Then move the other 2 two to a cha_fan with a 2/1 splitter I have?

Could a factory closed loop cooling system be mounted completely outside of a case?...where no hot air from the computer flows into or out of it? (All it gets is the ambient air temp from outside of the case and the inside of the case gets none of the radiators hot air.)

anything is possible, you just need to cut(mod) the case so that you can route the hoses through it ( ie: a notch in side cover or top of case) or perhaps your case has the rear frame bolted on, then all you'd need to do is remove the frame rail, then re-install afterwards...

I'm sorry I missed the change in case. If I had seen it I would have recommended you look for a different case or cooler. The only place that cooler is going to fit is in the front, and it will not cool well. If you really like that case I'd get a different cooler - either a good air cooler or a AIO with a single 120mm radiator, mounted in the rear. You don't need extreme cooling.

Fractal Design's Define C is capable of so much more than the Masterbox, which kind of makes me sad in a way because Coolermaster used to make really good cases...

I just bought the 760T Case and now I'm buying the ram. Will Corsair Vengeance LPX 32GB (2x16) DDR-3000 CL16 ram work for my machine? I'm asking twice because I'm no longer trying to listen to myself and throw more money down the drain.

Yes, that RAM should work fine, and actually leaves you with upgrade room to 64GB in the future should you need it

I bought the new case, I got a 780T as the 760T on Amazon would take a while to be delivered. I put everything in that case and it's up and running. I have a few questions, it has a fan control button which I plugged into the Sata connector and the fans into the mb cpu fan connectors. Is this correct? Also, I have 3 fans connected into a single hub, from the watercooler, that connect into a single cpu fan motherboard spot. Is that correct as well?

Got it sorted. Love this new case, so much bigger and all my things I bought actually fit. lol
